Application filed July 2S, 1919. Serial No. 313,841.

T0 all whom t may concern:

Be it known that I, WALTER F. GoDDARD, citizen of the United States, residing at Somerville, in the county of Middlesex, and State of lliassachusetts, have invented new and improved AslrSiters, of which the following is a speciiication.

This invention relates to a new and improved ash sitter and consists in the novel construction and arrangement of parts hereinafter described. and claimed.

Referring to the drawings wherein like characters indicate like parts wherever they occur f l Figure 1 is afront elevation of an' ash sitter constructed in accordance with my invention, showing the ash sitter lin position upon an ash-can;l f

Fig. 2 is a side elevation of the I' parts shown in Fig. 1; l K

Fig. 3 isa :vertical sectional kview on the line 3-3 of Fig. 2, looking in the direction ofthe arrow, the lower partof .the ash can being removed and the yparts of the ash sitter being shown on a scale larger than they appear in Fig. 2, in order to illustrate clearly the various parts of the device, there being represented in the ash pan the cinders that have been returned intok the ash pan after theL sifting operation; f

Fig. 4 is a detailperspective view of the screen, ash pan support, and ash paint-he latter being shown separated from its support tor the sake of illustrating the parts;

Fig. 5 is a vertical sectional view on the line oi' Fig.` 1,'flooking in the direction et the arrow, showing the shaft or spindle upon which the `screen-carrier plates are mounted, and also showing the'screen and the ash pan and the unscreened ashes and cinders in the pan. l

1 represents an ash can having a circular top Such structure serves as a support tor my improved sitter and as a receptacle for the siited ashes. i y

My new ash sitter comprises a base or support 3 and a casing 4, see Fig. 5, which carries and houses the operating mechanism The base 3, as shown, consists of a circular plate provided with a depending iiange 6, constructed to be slid down about the top 2 of the ash can, see Fig. 3, permitting the plate or base y-3 to rest upon and.y thus be supported by the top 2..'The

end wall 4 ofthe casing 4, as shown, is

correspond to the end wall.

.parts of the casing thus described may be generally circular, except atv the bottom where the walls are extended out of the circular plane as at 7, 7, see Fig. 3. The side walls 8, 89, consist of plates shaped to The several madeot s heet metal and secured together in any desired way common in the art.

As shown, the plate`3 is cut away between the ends 7, 7 of the wall 4 and the said plates 8, 8, as at 9, see Figs. 3 and 5, to provide a smooth and unbroken passagevway for the ashes from the casing to the can.

An opening is formed near the bottom of the side wall 8a, or front wall, adapted to bexclosed by a door 10, see Fig. 1, that is larger than saidv opening. vThe door 10 is hinged at its bottom by hinges 11, 11, to v the plate 8,

A button 12 carried at the top of the door serves to lock the door in place when not unlocked and dropped down to permit the n insertion or removalfof the ash pan, 13, see

Fig. 4.

A shaft or spindle 14 has its ends rotatably mounted in holes in or bearings cai'- ried by the side plates 8, 8a. A crank armr 15 has one end secured upon the projecting end of the spindle 14 outside the plate 8, and a handle 16 secured to the other end of said crank arm provides means for turning the spindle or shaft 14 and the parts carried thereby. f

17, 17 a represent circular plates mounted upon and secured to the spindle or shaft 14 to turn withv the latter. The plates 17, 17a are spaced apartr and their lower sides are truncated as at 18, these lines constituting in a general way 'a chord of their respective circles; The edge 18 in the front plate is further cut away as at 18, Fig. 3, to allow the ash pan to be slid under it, see Fig. 5, and against the plate 17. A flat plate 19, see Fig. 4, is secured atone of its sides to the edge 18 ofthe plate 17.

Referring to the plate 19 is bent upk as at 2O while the opposite end is bent up as at 21, the latter being shorter than the Jformer. The plate 19, when the parts are in the position shown in Fig. 3, coincides with the bottom of the opening in the plate 8a that is closed by the door 10, so rthat by ldropping the door down on its hinges, the ash pan 13 can be slid upon the plate 19, the ends 20, 21. being spaced Fig.` 3, the left-hand end of apart sufliciently to receive the ash pan between them. In this position the ash pan is lsecured against Vlateral displacement when the door 10 is closed by the plate 17 on one side and by the plate 8, see Fig. 5, onthe other.

22 to 30 represent a series of small rods arranged between the plates 17, 17 a, and having their ends secured to said plates. `These rods are positioned at increasing distances from thefspindle or shaft 111, theA rod 22 be- ,ing the nearest while the rod isi` the most distant A strip of wire Jfabric 31 is arranged between theplates, 17 ,.17a mounted Venponand secured.y to the rods22to 30, one yend of this strip being secured to the rod 2,2 -avhile the opposite end of the-strip is securedito the rod 30. This strip constitutes .the screen,:the nieshesfoi which are 'selected to permit the ash; to pass tlnough,but: to retain the cinders or uncomminuted particles.

In operation, the ash pan .13` is takenzfrom .the stove, the :door 10 of the Vcasing is A.dropped down, and the pan with; its contents rslid in place upon` the plate 119 `betweenjthe upturned ends 20, 21. This brings oney end sof the pan under the rod 22,A see Fig. 3, while :the other end olf-the pan is directly beneath the rod 32 whose ends are securedto the -plate 17, 17a. These rodswprevent the pan from dropping off the `plate 19ltoward the spindle `14. The door 10 is then closed and fthe sifting unit, including the pan and its contents, turned slowly in the direction of the arrow in gFig. 3, by'rneans `of the handle .16, in `one conipletecycle. The positionof thepan during this operationl can easily .be seen byiinerely turning the drawings. As thefpaninioves to the left inFig. 3, in the digrectioniof the arrow, about the spindle `111, .the contents of thepan are gradually spilled `upon the screen, inthe direction or' the arrow in Fig. 3, at the end of the ashpan,:the ash passing throughthe screen into thecan as indicated by the arrows in Fig. 5. As ythe pan coinpletes'its cycle and duringthe latter part of its return tothe initial posivtion shown in Fig. 3, the cinders and other material retained by the screen 31 runsoff Athe screen over the rod 22 into the panpand can be removed with the latter.

The hole cut in the plate -Sn covered by the door 10, as well as the opening formed by the cut-away portion 18a of the front plate 17a, are usually about the same size, andare sufficient to permit the ash pan to pass through said openings when the openings register, thatl is, Whentheparts are in "the position shown in Fig. 3.

` Having thus explained-the natureof my invention and described a Way of constructingv and using the same, though without at'- ternptingto set forth all of the V"forms'in which it may be made, or all of the modes of its use, what I claim and desire to secure by Letters Patent is:f-

.i r1. Anf ash sitter.k comprisinga rcasing and a1 rotatable unit including two similar heads, means lforfsupporting anaash `pan between `said heads, iand ,a :screenextending from one -headitofthe other. with itsends terminating adjacent opposite sidesfoffcthe pan support `and in different horizontal.v planes, said screen extending 1 about i the axis of the unit en .a line that :gradually approaches -said axis from its receiving toits delivery'l end.
